A Course Reference Number, often abbreviated CRN, is a unique identifier assigned to a specific class section at an educational institution. This is in contrast to a course number, which follows other conventions and is used to refer to the course itself, instead of a specific section of the course. CRNs are used during the registration process to identify the section of a course the student wishes to register for.

Famous quotes containing the words reference and/or number:
“If we define a sign as an exact reference, it must include symbol because a symbol is an exact reference too. The difference seems to be that a sign is an exact reference to something definite and a symbol an exact reference to something indefinite.”
—William York Tindall (1903–1981)
“The serial number of a human specimen is the face, that accidental and unrepeatable combination of features. It reflects neither character nor soul, nor what we call the self. The face is only the serial number of a specimen.”
—Milan Kundera (b. 1929)
